    Abstract: An electronic device includes a processor coupled to a battery and to determine whether the battery is being charged or discharged. If the battery being is being discharged, the processor operates to calculate an amount by which the battery has discharged since a preceding calculation of remaining capacity of the battery, compensate the amount by which the battery has discharged for a condition of the battery, and calculate a remaining capacity of the battery as a function of the amount by which the battery has discharged. If the battery is being charged, the processor operates to calculate an amount by which the battery has charged since a preceding calculation of remaining capacity of the battery, compensate the amount by which the battery has charged for a condition of the battery, and calculate the remaining capacity of the battery as a function of the amount by which the battery has charged.

    Abstract: Disclosed is a method of locking a locked loop quickly, including receiving an input signal having an input frequency, and generating an intermediate signal having an intermediate frequency intended to be equal to a geometric mean of the input frequency and a desired frequency, but not equal. Results of division of the desired output frequency by the intermediate frequency are estimated, producing a first divider value. A first locked loop utilizing a controllable oscillator is activated. A divider value of the first locked loop is set to the first divider value, and the intermediate signal is provided to the first locked loop, so that when the first locked loop reaches lock, the controllable oscillator produces the desired frequency. When the first locked loop reaches lock, a second locked loop that utilizes the controllable oscillator is activated, the first locked loop is deactivated, and generation of the intermediate signal is ceased.
